1737 Household Valuation

[figheadair]

Truss: According to google books/etymological dictionary of scottish language a truss was a ribbon which ladies wore inside their clothes in order to tie up their petticoats,when working.
In medicine it is a strap with pads to keep the hernia in place !!!!
I, pesonally, would stick to the ladies.

But in this case is more likely to have been an Anglicisation of the Gaelic truibhas - trews.
